Combatants in a battle of 20 kings documented in the Rgveda lived in the vicinity of Sarasvatī river basin. Together with this terrestrial battle, another battle has been raging on the hydrological front. Detailed review of the ongoing collision of two continental plates which created the Himalayas is presented. Two plate tectonic events which created Yamuna Tear Fault and Satluj Tear Fault have shown the principal cause for the migrations of these tributaries away from Sarasvatī river which is now called Sarsuti-Ghaggar-Hakra-Nara. Decipherment has provided thousands of words which detail the professional competence of artisans, lapidaries, smiths, smelters, miners, assayers of metal, seafaring merchants, wholesale merchants and formation of guilds which instituted the ethic of shared commonwealth. The Mohenjo-daro priest has been identified as Potr, 'purifier' one of 16 Rtvij from Rgveda times. This functionary of the nation is called in Meluhha Poddar, Potadara 'treasurer, assayer of metals.' Surprise! Indus Script Corpora of over 8000 inscriptions have turned out to be veritable documentations of wealth-accounting ledgers of guilds of a nation.
